Jose Manuel Villarreal (Villarreal) appeals his convictions for one count of conspiracy to possess with the intent to distribute more than 500 grams of cocaine and one count of aiding and abetting the possession with the intent to distribute more than 500 grams of cocaine. Villarreal contends that there was insufficient evidence presented at trial to prove beyond a reasonable doubt that he intentionally possessed, or that he conspired with co-defendants Ramon Perez-Martinez (Perez) and Rosa Idalia Trevino (Trevino) to possess with the intent to distribute, more than 500 grams of cocaine. Villarreal argues that the Government’s case was primarily based on the unreliable testimony of Perez and Trevino. He contends that the co-defendants’ testimony was inconsistent and failed to prove the essential elements of the offenses beyond a reasonable doubt.

Because Villarreal moved for a judgment of acquittal in the district court, we review the sufficiency of the evidence to determine whether, considering all the evidence in the light most favorable to the verdict, a reasonable trier of fact could have found that the evidence established guilt beyond a reasonable doubt. United States v. Mendoza, 226 F.3d 340, 343 (5th Cir. 2000). In cases involving a conspiracy, the “conviction may be based upon the uncorroborated testimony of a co-conspirator, even when that testimony is from one who has made a plea bargain with the *346 government, provided that the testimony is not incredible or otherwise insubstantial on its face.” United States v. Gadison, 8 F.3d 186, 190 (5th Cir. 1993). A witness’ testimony may be inconsistent, but sufficient, nonetheless. United States v. Greenwood, 974 F.2d 1449, 1458 (5th Cir. 1992).

Considering all the evidence in the light most favorable to the verdict, there was sufficient evidence presented at trial to prove that Villarreal intentionally possessed, and that he conspired with Perez and Trevino to possess with the intent to distribute, more than 500 grams of cocaine. The Government introduced telephone records showing a pattern of telephone activity corroborating the testimony of Trevino. Perez and Trevino’s testimony was also corroborated by other witnesses at trial, including the surveillance officers and the confidential informant. Accordingly, Villarreal’s convictions are AFFIRMED.
